Hello. I have gone through your question and understand your concern. Firstly, Low sperm count can be due to various causes some very common causes are smoking, drinking, drugs, overweight, infection, trauma to the testicles to something unexpected like wearing very tight clothing, exposing your testicles to radiation or heat. If you are exposed to any such factor that may cause low sperm count try to eliminate it that will eventually bring back your sperm count to normal. Good nutrition is a key to healthy sperm count so continue taking A to Z tablets and vitamin B 12 injection for not just sperm health but also total well being. Secondly, infertility in men is as common as infertility in females so most issue concerning low sperm count can be treated. Just like how the female infertility drugs induce ovulation, same way hormones are used for men. It all depends on underlying cause, have a conversation with your treating doctor about choice of treatments and try to eliminate any risk factor you are exposed. Good luck. Hope your concern is answered. Thank you.
